Abstract: In order to explore the possibility of aquaculture using concentrated seawater form seawater desalination, the immune stress response of Litopenaeus Vannamei in concentrated seawater was studied in this paper. Concentrated seawater was prepared by adding table salt to natural seawater. The salinity 40 and 36 were as experimental group and compared with the natural salinity 30. Litopenaeus Vannamei were acclimated for 0, 2, 6, 12, 24, 48 and 96 hours at different salinities, and the serum protein concentration, the activity of acid phosphatase, superoxide dismutase, serum lysozyme and the time of serum blood coagulation were determined and analysed at different salinities. The result showed that the serum protein concentration and acid phosphatase activity of Litopenaeus Vannamei caused by concentrated seawater decreased significantly (p<0.01), the time of serum blood coagulation were significantly prolonged (p<0.01), but that on serum lysozyme and superoxide dismutase activity were not significant (p>0.05).
